Gearing for LO206 tracks in my area (Illinois, Wisconsin)

Hello,

I just moved to the NW burbs of Chicago and run the LO206 Masters class.

Can anyone give me ball park gearing for the following tracks?

Badger
Concept Haulers
Kart Ciruit Autobahn
Road America
Shawano

Also, if anyone has run Blackhawk, Ozarks or Gingerman, that gearing would be appreciated also as I plan to run some big tracks as soon as I get up to speed in the Midwest.

Thanks in advance.

In Sr we run around 3.40 for CHMS. At Autobahn, we are about 3.55 depending on the layout. These should get you close.
